The second valve body 71 is formed in an elastically deformable annular shape having a radial outer end as a free end. The second valve main body 71 is an annular shape arranged coaxially with the container shaft O. The radial outer end portion of the second valve main body 71 is in contact with the portion of the lower surface of the top wall portion 45 that is radially outer side of the second outside air introduction hole 45a so as to be detachable from below over the entire circumference. .. As a result, the second valve main body 71 freely closes the second outside air introduction hole 45a from the inside of the inner plug main body 41.

In a state where the second valve body 70 opens the second outside air introduction hole 45a, the first outside air introduction hole 32a and the second outside air introduction hole 45a communicate with each other through the inside of the inner plug main body 41. As a result, the second outside air introduction hole 45a communicates the outside of the inner plug 40 with the first outside air introduction hole 32a. By communicating the outside of the inner plug 40 with the first outside air introduction hole 32a, the outside of the container body 20 and the outer container 21 pass through the intake hole 21b, the first outside air introduction hole 32a and the second outside air introduction hole 45a. Communicate with the inside.

On the other hand, in a state where the second valve body 70 closes the second outside air introduction hole 45a, the first outside air introduction hole 32a and the second outside air introduction hole 45a are blocked. That is, the second valve body 70 switches the communication between the first outside air introduction hole 32a and the second outside air introduction hole 45a and the shutoff thereof. As a result, the second valve body 70 switches the communication between the outside of the container body 20 and the inside of the outer container 21 via the intake hole 21b and the blocking thereof.

The second valve body 70 allows air to flow into the inner plug main body 41 from the outside through the second outside air introduction hole 45a, and allows air from the inside of the inner plug main body 41 to the outside through the second outside air introduction hole 45a. Functions as a check valve that regulates the outflow of air. The air that has flowed into the inner plug main body 41 from the outside through the second outside air introduction hole 45a is the content of the outer container 21 through the first outside air introduction hole 32a formed in the inner cap 30 and the intake hole 21b formed in the outer container 21. It flows into the container 22.

Next, a method of using the coating container 10 will be described. First, the user of the coating container 10 removes the outer cap 50. As a result, the pressing by the outer cap 50 of the rotary coating body 42 is released, and the contents can flow into the inside of the holding cylinder portion 46 from the communication port 46a. After that, the user squeeze-deforms (elastically deforms) the outer container 21 inward in the radial direction. As a result, the inner container 22 is deformed inward in the radial direction together with the outer container 21 to reduce the volume, so that the internal pressure of the inner container 22 rises. Then, since the first valve main body 61 separates upward from the upper surface of the second annular portion 35, the content introduction hole 35a is opened and the communication port 46a and the inside of the inner container 22 are separated from each other. It communicates through 35a, the inside of the inner connecting cylinder portion 37, and the inside of the second fitting cylinder portion 43. As a result, the contents contained in the inner container 22 flow into the inside of the holding cylinder portion 46 through the communication port 46a. Therefore, the contents adhere to the outer surface of the lower end portion of the rotary coating body 42. In this state, while pressing a part of the rotary coating body 42 protruding from the holding cylinder portion 46 against the coated portion (not shown), the rotary coating body 42 is rotated along the coated portion. As a result, the content can be distributed to the outer surface of the protruding portion of the rotary coating body 42, and the content can be applied to the portion to be coated via the outer surface of the rotary coating body 42.

By stopping or canceling the squeeze deformation of the outer container 21, when the increase in the internal pressure of the inner container 22 is stopped or the internal pressure of the inner container 22 decreases, the first valve main body 61 is restored to its original state by the restored deformation of the elastic arm 63. Return and sit on the upper surface of the second annular portion 35. As a result, the content introduction hole 35a is closed again, and the communication between the communication port 46a and the inside of the inner container 22 is cut off. Therefore, the inflow of the contents from the inside of the inner container 22 to the inside of the holding cylinder portion 46 is stopped.

Further, by releasing the squeeze deformation of the outer container 21, the outer container 21 begins to be restored and deformed, so that a negative pressure is generated between the outer container 21 and the inner container 22. Then, this negative pressure acts on the second valve body 70 through the intake hole 21b and the first outside air introduction hole 32a, and the radial outer end portion of the second valve main body 71 is separated downward from the lower surface of the top wall portion 45. As a result, the second outside air introduction hole 45a is opened and air flows into the inside of the inner plug main body 41 from the outside through the second outside air introduction hole 45a, and this air flows into the first outside air introduction hole 32a and the inside of the inner cap 30. And through the intake hole 21b, it flows into the space between the outer container 21 and the inner container 22. As a result, even if the outer container 21 is restored and deformed, the outer surface of the inner container 22 can be separated from the inner surface of the outer container 21 and the inner container 22 can be kept in a state of being reduced in volume and deformed. As a result, the inner container 22 is reduced in volume and deformed as the contents decrease.

The user may apply the contents via the rotary coating body 42 in a state where the outer container 21 is squeeze-deformed, or after the outer container 21 is squeeze-deformed, the outer container 21 is restored and deformed. Later, the contents may be applied via the rotary coating body 42.

As described above, according to the present embodiment, the inner container 22 is reduced in volume and deformed as the contents decrease. Therefore, even if the content is reduced, the inflow of air into the inner container 22 is suppressed, and the state in which the inner container 22 is filled with the content can be maintained according to the reduced volume. As a result, regardless of the degree of reduction of the contents, if the inner container 22 is slightly deformed by the squeeze deformation of the outer container 21, the contents can be easily discharged from the inner container 22 by the increase of the internal pressure. Therefore, the user can easily send the contents in the inner container 22 to the inside of the holding cylinder portion 46 via the communication port 46a. As a result, the user can easily apply the contents without, for example, placing the application container 10 in an inverted position. As a result, according to the present embodiment, a coating container 10 in which the contents can be easily coated can be obtained regardless of the posture. The coating container 10 of the present embodiment can apply the contents in, for example, an upright posture, an inverted posture, a sideways posture, and the like.
Further, since it is possible to suppress the inflow of air into the inner container 22, it is possible to suppress the deterioration of the contents due to the air.

Further, according to the present embodiment, a first valve body 60 for switching communication between the inside of the inner container 22 and the inside of the holding cylinder portion 46 via the communication port 46a and the shutoff thereof is provided. Then, the first valve body 60 allows the contents to move from the inside of the inner container 22 to the inside of the holding cylinder portion 46, and moves the contents from the inside of the holding cylinder portion 46 to the inside of the inner container 22. It is a check valve that blocks. Therefore, when the outer container 21 is squeeze-deformed, the contents can be discharged from the inside of the inner container 22, while when the outer container 21 is restored and deformed, the first valve body 60 puts the contents inside the inner container 22. The inflow of air can be further suppressed. As a result, the state in which the inner container 22 is filled with the contents can be more preferably maintained, and the contents can be more easily applied. In addition, deterioration of the contents can be further suppressed.
Further, the first valve body 60 can prevent the contents once discharged from the inner container 22 from returning to the inner container 22 again. Therefore, deterioration of the contents in the inner container 22 can be further suppressed.

Further, according to the present embodiment, a second valve body 70 for switching communication between the outside of the container body 20 and the inside of the outer container 21 and the shutoff thereof is provided via the intake hole 21b. Then, the second valve body 70 shuts off the outside of the container body 20 and the inside of the outer container 21 when the outer container 21 is squeezed and deformed, and when the squeezed outer container 21 is restored and deformed, the container body 20 The outside and the inside of the outer container 21 are communicated with each other. Therefore, when the outer container 21 is squeeze-deformed, it is possible to prevent the air between the outer container 21 and the inner container 22 from flowing out to the outside of the container body 20 through the intake hole 21b. Thereby, when the outer container 21 is squeeze-deformed, the air pressure between the outer container 21 and the inner container 22 can be maintained. Therefore, even when the inner container 22 is deformed in a reduced volume and is greatly separated from the inner surface of the outer container 21, the inner container 22 can be easily deformed via air without significantly deforming the outer container 21. can. On the other hand, when the outer container 21 is restored and deformed, the air outside the container body 20 can flow between the outer container 21 and the inner container 22, so that the inner container 22 is suitably maintained in a reduced volume deformed state. can do.

Further, according to the present embodiment, the intake hole 21b is formed in the mouth portion 21a of the outer container 21, and the first outside air introduction hole 32a formed in the inner cap 30 and the second outside air introduction formed in the inner plug 40. It communicates with the outside of the inner plug 40 through the hole 45a. As a result, air can flow between the outer container 21 and the inner container 22 from the second outside air introduction hole 45a formed in the inner plug 40. Therefore, when the user uses the coating container 10, it is possible to prevent the second outside air introduction hole 45a from being blocked by, for example, the user's hand. Therefore, it is easy to appropriately allow air to flow between the outer container 21 and the inner container 22, and it is easy to preferably maintain the inner container 22 in a state of being reduced in volume and deformed.

Further, according to the present embodiment, the rotary coating body 42 is pressed by the outer cap 50 toward the inside of the container body 20 along the container axis O direction and pressed against the inner surface of the holding cylinder portion 46, and the communication port is communicated. Block 46a. Therefore, by attaching the outer cap 50, it is possible to prevent the contents from leaking from the communication port 46a into the holding cylinder portion 46. In addition, it is possible to prevent the contents from leaking to the outside of the coating container 10.
